PBoC conducts CNY 600bln overnight reverse repo operation

Open market operations of this kind are the PBoC's routine channel for managing interbank liquidity, and the size of a single operation is less informative than the net injection once maturing operations are counted. Historically, larger gross offerings have tended to cluster around predictable liquidity drains: tax payment dates, government bond issuance, quarter-end regulatory checks, and holiday cash demand, and in those episodes the operation rolls off rather than signalling any shift in stance. The distinction that matters is between offsetting a temporary shortage, which leaves money market rates anchored near the policy corridor, and persistent net injection, which has on past occasions preceded or accompanied a softer stance and shown up in the 7-day repo rate fixing below the corridor midpoint. Worth noting that overnight tenor operations of this size are less common than the standard 7-day offering, and have tended to appear when the bank wants same-day smoothing without a week-long commitment. The follow-ons are the maturity schedule against this operation, the 7-day repo rate relative to its policy anchor, and any shift in the medium-term lending facility rate, which carries the actual signal. As a daily operation rather than a rate decision, this is plumbing, not policy.
